Leading Node.js API Development ServicesAPI Development
Build production-grade APIs in 8-12 weeks. We ship secure, scalable Node.js backends used by 200+ products globally.
IRPR builds production Node.js APIs using Express, Fastify, and NestJS. We handle REST, GraphQL, WebSocket, and gRPC protocols for any scale.
You get a fully functional API with CI/CD pipeline, automated tests, and monitoring in 8-12 weeks. Pricing starts at $80K and goes up to $250K depending on complexity. We comply with HIPAA, PCI-DSS, and SOC 2 standards.
Our clients include CTOs at Series A startups who need a scalable backend in weeks. Engineering leads at fintech companies requiring PCI-compliant APIs. Product managers at healthcare platforms building HIPAA-compliant patient data APIs. Tech founders launching SaaS MVPs with multiple third-party integrations.
Types of software we ship.
REST API Development
Build stateless CRUD APIs with Express.js. We use OpenAPI 3.0 spec for full documentation and automated client generation.
GraphQL API Development
Create flexible, type-safe APIs with Apollo Server or Yoga. Resolve complex data relations without over-fetching.
Microservices API Architecture
Decompose monolithic backends into independent Node.js services linked with RabbitMQ or Kafka.
Real-Time API (WebSocket)
Implement bi-directional communication using Socket.io or native WebSocket. Ideal for live dashboards and chat.
Serverless API (AWS Lambda)
Run Node.js functions on AWS Lambda with API Gateway. Auto-scale to zero cost when idle.
Third-Party API Integration
Connect your app to Stripe, Twilio, HubSpot, and 50+ providers. We cache and rate-limit by default.
API Gateway Development
Centralize authentication, throttling, and logging with Kong or Express Gateway. One entry point for all services.
Internal API (Backend for Frontend)
Design private endpoints tailored to your React or Vue frontend. Reduce payload size and speed up development.
We build for every business type.
SaaS Platforms
Fintech Companies
Healthcare Organizations
E-commerce Brands
Enterprise Systems
Results That Matter for Leading Node.js API Development Services
Our Node.js APIs power real products with measurable outcomes.
Every API we ship is built for performance and reliability. We track uptime, latency, and throughput from day one.
Our stats come from 200+ projects across 50 countries. We maintain a 98% on-time delivery rate and average 12 weeks to MVP.
The Difference Between a Generic Dev Shop and IRPR
Not all Node.js API development providers deliver the same quality. Here is the contrast.
Many shops start coding without a clear plan, leading to cost overruns and delayed launches. They use junior developers and skip monitoring.
IRPR works differently. We define scope in a fixed-price Roadmap, assign senior engineers, and provide full observability from the first sprint.
- No fixed pricing – hourly billing only
- No dedicated project manager
- Unclear timeline – often 6+ months
- No monitoring beyond basic logs
- No API documentation
- Code ownership is ambiguous
- Fixed price after 2-week Roadmap phase
- One PM per project with weekly demos
- 8-12 week guaranteed timeline
- Sentry error tracking + Datadog performance monitoring
- OpenAPI 3.0 docs auto-generated
- Full code ownership – you own everything
Our 4-Phase Process for Leading Node.js API Development
We follow a proven 4-phase process to deliver your API on schedule.
Each phase has clear deliverables and a decision gate before moving forward. This eliminates surprises.
The timeline is 8-12 weeks total, with the first 2 weeks dedicated to planning.
What Ships With Every Node.js API Project
Every delivery includes everything you need to run and maintain the API in production.
You get more than just code. We hand over a complete system with monitoring, documentation, and compliance artifacts.
All deliverables are tested and documented before we hand them over.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Automated unit and integration tests with Jest
- API documentation via Swagger/OpenAPI
- Sentry error tracking
- Datadog performance monitoring
- Docker containerization
- Deployment scripts for AWS/GCP/Azure
- One month of post-release support
- Compliance documentation (SOC 2, HIPAA)
What we ship in this practice.
Payment API for Fintech Startup
Built a PCI-DSS compliant payment gateway API using Express.js, Stripe Connect, and PostgreSQL. The API processes 10,000 payments per hour with 200ms latency.
Healthcare Patient Data API
Developed a HIPAA-compliant patient records API with Fastify and MongoDB. Reduced data retrieval time by 60% compared to the legacy REST endpoint.
Real-Time Inventory API for E-commerce
Created a WebSocket-based inventory sync system using Socket.io and Redis. Cut inventory update delays from 30 seconds to under 100ms.
SaaS Analytics API
Designed a GraphQL API for a multi-tenant analytics platform using Apollo Server and PostgreSQL. Enabled clients to query custom metrics in under 1 second.
Logistics API for Route Optimization
Integrated Google Maps and HERE APIs into a Node.js microservice. Saved logistics company $500K annually by reducing fuel costs.
Media API for Video Streaming
Built a scalable video upload and transcoding API using Node.js, FFmpeg, and S3. Handles 500 concurrent video uploads with auto-thumbnail generation.
Why teams hire us.
Fixed Price, Not Hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
Senior Engineers Only
All developers have 10+ years of Node.js experience. We skip juniors – you work with architects who have shipped 200+ products.
8-12 Week Delivery
MVP ships in 8-12 weeks, not months. Our sprint cycles are 2 weeks, with working code demoed every Friday.
Compliance Built In
HIPAA, PCI-DSS, and SOC 2 are standard. We bake security into the API design, not as an afterthought.
Full Code Ownership
You own all source code, documentation, and IP. No licensing fees, no vendor lock-in.
Post-Release Support
We provide 30 days of active support after deployment. Monitoring tools (Sentry, Datadog) are handed over so your team can maintain.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
